The Anbernic RG353V-V2 panel is a 3.5 inch 640x480 MIPI-DSI LCD panel.
It's based on the ST7703 LCD controller just like rocktech,jh057n00900.
It's used in a 2nd revision of the Anbernic RG353V handheld gaming
device. Like the first revision of the RG353V the control chip is known
but the panel itself is unknown, so name it for the device.
